For 20 odd years, and many were really odd, I wore my hippie uniform of tie dye and boho skirts, with a tiny collection of work clothes for the newspaper.

I'm a career changer into bodywork, and will have most clients in private practice.
I can't look like a yoga teacher, but I need about the same flexibility in movement. ( I do floor based shiatsu and Thai as a major portion of my work)
eventually, I'll add other therapists to the office, and I'd like to have a look that is somewhat uniform.

I don't want a spa uniform or scrubs.
I also don't want tshirts and yoga pants.

I'm also developing a look for who I am now.

I'm not power suit woman. I don't wear heels, and won't.
But, I don't see a middle between suit and workout wear.

Right now I use Thai fisherman pants and they are ideal in the treatment room.
That is what I keep for clients, too.
I need a top that works with them, and likely I'd just get six of the same.
I'd like to have 3/4 sleeves, or a slight bell that I can fold up to use my elbows.

Could you wear pants that are stretchy (thinking a stretchy twill) so they have some give to them, but that shrink back to looking more like slacks? Or just generously-sized casual slacks? (generous in the hips and buns, I mean)

I'll keep looking. Peasant blouse isn't quite what I'm thinking, but it's in-between that and that last V-necked thing. Almost like what they wore in the 70s, the white muslin with white embroidery on it with a keyhole neckline. I'm sure you have seen them...
